How long can the wire connections be on a SPI bus? The reason I am
asking this is I want to interface to a MAX6674 from Maxim to a BS2
40P that is going to be 6 feet away or more with shielded, twisted
pair cable. Will this work or am I pushing this technology? Should I
use series termination on the SPI bus to slow the edges down to
minimize overshoot/undershoot? The MAX 6674 is going to be located as
close to the thermocouple as possible to improve it's accuracy.
